I use Windows Server 2003 SP2. When logged in as an administrator, I can double click on a .jpg file, and it will open in the default application, which I can change through Folder options > File types. However, when logged in as an ordinary user, I get a "no application associated with this file type" error when I double click on a .jpg file (although I can right-click on it and select "Open with" to open it in an application manually), and when I try to change the file association through Folder options > File types, the Change buttons are disabled (greyed out) for the .jpg type. How can I fix this?
